Of those twenty, only four are in the category “public school with a dedicated computer lab” \u2013 the four red squares in the Venn circle on the left.\u00a0 4\/20*100 = 20%.\u00a0 Answer = A<\/strong>.<\/p>\n <\/p>\n 2) There are 14 schools in one of the two Venn circles \u2013 those are the schools either with dedicated computer labs or a computer in every classroom.\u00a0 Of those schools, 6 are public: the four red squares in the left Venn circle, and the two in the right Venn circle.\u00a0 6\/14*100 = 42.9%.\u00a0 Answer = D<\/strong>.<\/p>\n <\/p>\n 3) There are 12 in the left Venn circle (including the overlap region) \u2013 those are the schools with dedicated computer labs.\u00a0 Of those, four are public schools \u2013 the four red squares in the Venn circle on the left.\u00a0 4\/12*100 = 33.3%.\u00a0 Answer = B<\/strong>.<\/p>\n <\/p>\n 4) When the overlap region is subtracted from the left Venn circle, the resultant lune holds the high schools with a dedicated computer lab and<\/span> without a computer in every classroom.\u00a0 There are nine schools in this region, of which 4 are public: the four red squares in that left-most lune.\u00a0 4\/9*100 = 44.4% Answer = E<\/strong>.<\/p>\n <\/p>\n 5) Evaluate the statements one by one.\u00a0 Statement I: Independent schools constitute the high percentage of high schools in Grangerville with both a dedicated computer lab and a computer in every classroom<\/em>.\u00a0 Schools with both a dedicated computer lab and a computer in every classroom are the overlap region of the two Venn circles.\u00a0 There are three schools in that region, and two are independent, so independent schools constitute the majority of that region.\u00a0 Statement I is true.<\/p>\n Statement II: Public Schools are tied for the highest percentage of high schools of Grangerville with a dedicated computer lab<\/em>. The schools with a dedicated computer lab are the left Venn circle, the whole of the circle including the overlap region.\u00a0 In this circle, there are 12 schools —- 5 parochial, 4 public, and 3 independent.\u00a0 Therefore, parochial schools only constitute the highest percentage of that region, and public schools are a clear second.\u00a0 Statement II is false.<\/p>\n Statement III:\u00a0 Public Schools constitute the highest percentage of high schools of Grangerville with either a dedicated computer lab or a computer in every classroom<\/em>.\u00a0 Schools with either a dedicated computer lab or a computer in every classroom constitute the combined area of the two Venn circles.\u00a0 There are 14 schools in that region —- 6 public, 5 parochial, and 3 independent.\u00a0 Public schools constitute the majority of that region.\u00a0 Statement III is true.<\/p>\n Answer = E<\/strong><\/p>\n <\/p>\n 6) There are 12 public high schools \u2013 the 12 red squares throughout the diagram, including those at the top.\u00a0 Of these, four are in the left Venn circle, which represents having a dedicated computer lab.\u00a0 4\/12*100 = 33.3%.\u00a0 Answer = B<\/strong>.<\/p>\n <\/p>\n 7) There are 12 public high schools.\u00a0 Of these, two are in the right Venn circle, which represents having a computer in every classroom.\u00a0 2\/12*100 = 16.7%\u00a0 Answer = A<\/strong>.<\/p>\n <\/p>\n 8 ) There are 12 public high schools.\u00a0 Of these, there are four in the left-most Venn lune (i.e. the left circle with the overlap subtracted).\u00a0 This region represents the schools that have a dedicated computer lab and do not<\/span> have a computer in every classroom.\u00a0 4\/12*100 = 33.3%.\u00a0 Answer = B<\/strong>.<\/p>\n <\/p>\n 9) There are 5 parochial schools in the diagram \u2013 the five blue circles.\u00a0 All five of these are in the left Venn circle, which represents having a dedicated computer lab.\u00a0 5\/5*100 = 100%.\u00a0 Answer = E<\/strong>.<\/p>\n <\/p>\n 10) There are 5 parochial schools in the diagram.\u00a0 Of these, four of them are in the left-most Venn lune, which represents the schools that have a dedicated computer lab and do not<\/span> have a computer in every classroom.\u00a0 4\/5*100 = 80%.\u00a0 Answer = D<\/strong>.<\/p>\n <\/p>\n 11) There are 3 independent schools in the diagram \u2013 the three green triangles.\u00a0 Of these, all three are in the left Venn circle, which represents having a dedicated computer lab.\u00a0 3\/3*100 = 100%.\u00a0 Answer = E<\/strong>.<\/p>\n <\/p>\n 12) There are 3 independent schools in the diagram.\u00a0 Of these, only one is in the left-most Venn lune, which represents the schools that have a dedicated computer lab and do not<\/span> have a computer in every classroom.\u00a0 1\/3*100 = 33.3%.\u00a0 Answer = B<\/strong>.<\/p>\n <\/p>\n <\/p>\n The post Data Insights Questions: Graphics Interpretation<\/a> appeared first on Magoosh Blog \u2014 GMAT\u00ae Exam<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" There are twelve practice questions in this set.
